I’m Torben Leth, a Business Central developer at Continia Software. I focus on tooling, AI-assisted development, and making BC run in places it probably shouldn’t.
This page collects my open-source work and community contributions.
Active Projects
AL Language Server for Claude Code
What: Native LSP integration that gives Claude Code full code intelligence for AL:
symbol awareness, Go to Definition, Find References, and call hierarchy.
Why it matters: Claude Code can now navigate your AL codebase like a developer would,
not just grep through files.
CentralGauge – AL Code Benchmark for LLMs
What: Open-source benchmark that tests how well AI models write AL code for Business Central.
57 tasks, containerized testing, two-pass evaluation.
Why it matters: Helps BC developers choose the right AI tools and understand model limitations.
BC WebClient MCP Server
What: MCP server that reverse-engineers Business Central’s WebSocket protocol,
letting AI assistants interact with BC like a human would.
Why it matters: Enables AI-driven ERP automation without custom extensions.

- 📦 GitHub
- 📦 npm
- 📝 Blog: MCP Servers for BC Developers (coming soon)
Business Central on ARM / Linux
What: Running BC development environments on ARM processors (Snapdragon, Apple Silicon)
and Linux through custom Wine builds.
Why it matters: Enables BC development on modern, power-efficient hardware.

- 📝 Blog: BC development on Snapdragon ARM (coming soon)
Serena MCP – AL Language Support
What: Contributed AL language server integration to Serena MCP,
enabling symbol-aware code editing for Business Central.
Why it matters: AI assistants can now understand AL code structure, not just regex patterns.
- 🔗 Merged PR #593
